Unfortunately, we do not sell a good replacement for this latch. The best options in our inventory are our 91-158 and 91-159, but there is no guarantee that they will work for you. Storm windows in general have been dying off for decades now and replacement parts are getting harder and harder to get a hold of. That's just the reality of the industry right now, unfortunately. Just something to keep in mind as you move forward on this project. |
